I'm happy to announce availability of Mango, a LR(1) parser generator for
release 3.0 of Self system. If you download Mango, be sure to check the
README file for last minute announcements.
Mango is available via mosaic: http://self.stanford.edu/papers/mango.html
and ftp: self.stanford.edu:/pub/Self-3.0/contrib/
Mango is documented in a 43 page Sun Microsystems Laboratories Technical
Report, TR-94-27. The postscript for this report can be found at the
above mentioned places. You may also request a hardcopy by writing to:

Mango is a parser generator that is included in Release 3.0 of the Self
system. Mango goes beyond LEX/YACC in several respects. First, Mango
grammars are structured, thus easier to read and map onto parse trees.
Second, Mango parsers automatically build parse trees rather than
merely provide hooks for calling low-level reduce actions during
parsing. Third, Mango automatically maintains invariance of the
structure of parse trees, even while grammars are transformed to enable
LR parsing. Fourth, Mango and the parsers it generates are completely
integrated in the Self object world. In particular, a parser is an
object. Unike YACC, several independent parsers can co-exist in a
We show how to generate a Mango parser and how to use it by means of an
example: a simple expression language. Furthermore, we show how to add
semantic properties to the parse trees that the Mango parser produces.
Mango is a realistic tool. A parser for full ANSI C was built with Mango.
